| 目的 观察交叉异位融合肾影像学表现。方法 回顾性分析12例交叉异位融合肾资料，分析该病影像学表现。结果 12例交叉异位融合肾包括L型5例，下异位型（Ii型）、S型及块状型（O型）各2例，甜甜圈型或盘状型（C-C型）1例；均表现为一侧肾窝空虚而对侧肾形态、位置大致正常，异位肾跨过中线与对侧肾融合，8例右向左、4例左向右融合；异位肾输尿管均跨过中线， 11例开口于对侧膀胱三角区、1例异位开口于前列腺。3例合并生殖系统畸形，其中单角子宫、双角子宫、隐睾各1例；2例合并下腔静脉异常，包括双下腔静脉、左下腔静脉各1例。结论 交叉异位融合肾具有特征性影像学表现；完整显示肾融合、输尿管走行及开口有助于准确诊断及分型。 |

| Objective To explore imaging manifestations of crossed ectopic fused kidney. Methods Data of 12 patients with crossed ectopic fused kidney were retrospectively analyzed, and the imaging manifestations of crossed ectopic fused kidney were observed. Results L type crossed ectopic fused kidney was detected in 5 cases, while inferior ectopic type (Ii type), S-shaped type and lump type (O type) ectopic fused kidney was found each in 2 cases, respectively, and doughnut or disc type (C-C type) ectopic fused kidney was noticed in 1 case. The ectopic fused kidney presented with empty one side renal cavity, while the morphology and position of the contralateral kidney were generally normal in all 12 cases, which crossed the midline and fused with the contralateral in situ kidney, including right to left crossed ectopic fusion in 8 cases and left to right crossed ectopic fusion in 4 cases. The ureters of the crossing kidney went across the midline, opened into the bladder trigone on the contralateral side in 11 cases or prostate in 1 case. Combined reproductive system abnormalities were found in 3 cases, including unicornous uterus, bicornuate uterus and cryptorchidism each in 1 case. Two cases were found complicated with abnormal inferior vena cava, including 1 case of both side inferior vena cava and 1 case of left inferior vena cava. Conclusion The imaging manifestations of crossed ectopic fused kidney had characteristics. Complete displaying of reveal fused kidney, ureteral course and opening was helpful to accurate diagnosis and classification of crossed ectopic fused kidney. |
